1 Claim. 1

This invention relates to propelling means for rowboats and has for oneof its main objects the provision of specially constructed oars orpropelling means which will replace the conventional cars in use at thepresent time.

Another object of the invention is to provide a device that is easilyoperated, durable and can be easily attached or detached from a rowboat.

With the above and other objects and advantages in view the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawings in which:

Figure 1 is a side elevation of an embodiment of the invention asapplied to a row boat.

Figure 2 is a view partly broken away on the line 2-2 of Figure 1.

Figure 3 is a detailed view on the line 33 of Figure 2.

Figure 4 is an end view of an embodiment of the invention.

Figure 5 is a top view on the line 5-5 of Figure 4 and Figure 6 is asectional view on the line 5-6 of Figure 5.

Referring more in detail to the drawings the reference numeral IDdesignates the row boat or similar craft to which the invention can beapplied, having sides l2 to which the anchor post 14- is secured bymeans of a clamp is formed on the lower end thereof. The clamp I6 isprovided with a set screw it to firmly fix the clamp to the side of theboat.

Formed on the upper end of the post 14 is the rectangular shaped housing2! having a curved top 22 and curved bottom 25.

The housing 28 has a removable plate 26 which is secured in place bybolts 28. Journalled in the top of the housing 20 is the shaft bolt 30,which is provided on one end with the gear 32 and on the other end withthe short upper arm 34. A spacer sleeve 36 is mounted on the shaft 30intermediate the housing 20 and the upper arm 34 and nuts 38 retain theelements as a unit assembly.

Pivotally connected to the upper arm 34 by means of the pivot 40 is thedrive link or rod 42, and a sleeve 44 on the pivot 4!! permits freeaction of the drive link 42V Also journalled in the housing 20 are theoppositely positioned alined bolt shafts 46 and 41.

Mounted on the shaft 46 is the long lower arm 58 which is spaced fromthe housing 26 by sleeve 59 and retained in place by the nut 52 on theshaft bolt 46.

Slidably mounted on the lower arm 48 is the sleeve 54, which acts as aself adjuster for water level stroke, and the pivot 56 pivotallyconnects the lower end of the link 42 to the sleeve 54.

The stock 58 of the paddle 62 is adjustably mounted in the sleeve 54,and retained in position therein after adjustment for blade depth bymeans of the set screw 60.

The paddle 62 is provided with a pivoted blade 64 which is pivoted at 66and permits the portion 64 to swing on top of water when it returns forthe stroke.

The bolt shaft 41 is provided with a gear 68 which meshes with the gear32 on the shaft 30. These gears operate to oscillate the arm 34 andoperate the paddle at proper water level.

A crank i0 is mounted on the shaft 41 and spaced from the housing 20 bythe sleeve 12 and a nut 14 retains these elements as a unit and thecrank handle 16 is secured to the crank by the nut 18.

The operation is as follows: The crank is rotated causing the gears torotate oscillating the paddle to propel the row boat. With paddlesmounted on both sides of th row boat, the row boat can be propelledforward in the usual manner with the hinged blade feathering the paddleson the return stroke.

Thus a device has been provided that will be easy to operate, thepaddles once adjusted for proper water depth will always be at properadjustment for propelling the boat and the boat will be of great benefitto fishermen since there will be no paddles or oars in the bottom of theboat to hamper their actions or oars in oarlocks that can be lost duringthe excitement of a catch.

It is believed that the operation of the device will be apparent tothose skilled in the art and it is to be understood that modificationsand changes in the combination of the various parts may be resorted toprovided they fall within the spirit of the invention or the scope ofthe ap pended claim,

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is:

A device of the character described, in combination with a boat,comprising a housing, means for securing said housing to a side of theboat, a long upper shaft and two short oppositely disposed lower shaftsjournalled in said housing, a short upper arm connected to said longupper shaft, a long lower arm connected to one of said lower shafts onthe same side of said housing at said short upper arm, a sleeve slidablymounted on said long lower arm, a link connected to the free end of saidshort upper arm and to an end of said sleeve, a gear on said uppershaft, and a gear on said lower shaft opposite to the lower arm on saidopposite shaft,

4 said gears adapted to mesh with each other to cause oscillation ofsaid shafts and said upper and lower arms, a crank mounted on said lastmentioned shaft outwardly of said gear to oscillate said shaft, andmeans in said sleeve for adjustably securing the stock of a paddletherein.
